2 Claims. (CI. 12-40) This invention relates to devices for gaging shoe soles in relation to instrumentalities for operating upon the soles, and it is herein disclosed as embodied in a lip cutting and scoring machine of the type illustrated and described in. United States Letters Patent No. 2,746,068, granted May 22, 1956, on an application filed in my name and of which this application is a division.

The present invention consists in the novel features hereinafter described, reference being bad to the accompanying drawings, which illustrate several embodiments of the same, selected for purposes of illustration, and the said invention is fully disclosed in the following description and claims.

:Fig. 8 is an elevation, as seen from the 'front of the machine, of the adjusting device shown in Fig. 7; and

Fig. 9 is a sectional view, taken on the line SIX-4X of Fig. 8.

Referring to Fig. l, the illustrated machine I'isprovided with a worktable 30 which constitutes the top .ofxa frame in the iormof a box-like housing or supporting, structure 32 having feet 34 adapted to rest upon ;-a work bench. The forward portion of the worktable-30 has ,fliSQlB supporting surface upon which an insole S (Fig. '5) can :be centered laterally of the machine by gage rolls 36 and38. The longitudinal position of the sole is determined by the engagement of its heel end with a gage 4il.- Associated with the worktable 3d are various marking orimpressing devices for operating on the under or grain surfaceof the sole S. One of these marking devicesis a die '42 for-impressing the manulacturers trademarkotr other identifying symbol upon the sole. A1'lOih1.'zdl 4.4- stampsthe width mark and still another die 46 stamps the size mark upon the sole. Also associated with the worlcta'b-le 301's a die 43 for:impressing a line of indentations known as score markings upon the grainsurfacetof thelsole to mark the position of the heelbreastline.

A plurality of tools in the form of pressern embers, carried by a vertically movable head 5il:(Fig., l,),.enga ge the upper or flesh surface of the soles to press the sole against the various'dies. Thesepresser members, -nutn bered 52,-54,-and da cooperate with, the dies. 42,44, and 46, respectively. .A toothed indenting:toobSScarried by the head. 50 cooperates with the die 48 .toiortntindentaengages a gpinlz zlii carried by platez a5 tions not only in the grain surface but also in the flesh surface of the sole to mark the heel breast-line. Two knives at (one of which appears in Fig. l) are also carried by the head 58 for making incising cuts intothc flesh surface of the sole to define the heelward ends of the channel lips which are to be cut by a. subsequent operation. indenting tools may, if desired, be substituted for the knives to make score marl tings instead of cuts.

The head 5% (Fig. 1) consists of a block having a pair of integral upstanding arms 68 (only one of which is shown), the upper end portions of which are pivotally connected by a pin 72 to the forward end of an arm 74. The rear end of the arm 74 is pivotally supported upon a transverse stationary pin "is secured in a pair of vertical walls 73 and 8t) (Fig. 2) extending up from the housing 32 and having horizontal flanges ill by which they are s ecured upon the housing. The lower portion of one of the arms 63 is pivotally connected by one of a pair of coaxial pins 82 to the forward end of one of a pair of arms 84 (only one pin 8-2 and one arm 34 being shown), the rear ends of the arms 8-4 being pivotaliy supported upon a transverse shaft 86 journalecl for free rocking movement in bearings formed in the walls 78 and 39 directly below the pin 76. It will be readily apparent from an ,inspection of Fig. 1 that the plane which includes the axes of .the pins 72 and 76 is always parallel to the plane which includes the common axis of the pins $2 and the :axis of the pin 86 and that, therefore, the plane which includes the axis of the pin 72 and the common axis of the pins 82 is always vertical, thereby insuring that the movement of the head 50 will take place in up-and-down path without tilting. in other words, the four axes define :a parallelogram and the assembly just described constitutes a parallel linkage, the upper link of which is the arm 74, and the lower link of which consists of the two arms 34 which move in unison and are always parallel :to the arm 74.

The raising and lowering of the head 5i is accomplished by means of a toggle mechanism operated by aneocentrie 92 (Fig. I) seemed a power driven shaft 94 under control of a clutch. The eccentric 92, through a connecting rod 96, drives a toggle pin which pivotally connects the adjacent ends of an assembly of toggle members comprising a lower link in the form of a yoke 109 and a pair -61 parallel upper links it'll! (only one of which is shown). T he yolre rill? has a pair of upstanding parallel arms 106 (only one of which is shown), the lower portion of this yoke being pivocally mounted upon a pm 110 having and portions which are secured in the arms 34, and the upper ends of the arms ,being piyotally connectedto the toggle pin 93. The upper e. s oftthe links W2 are pivotally mounted upon pin .lia't ing a central portion which is notched to clear the arm 7. 5. The end portions of the pin lid sec" 3' supporting arm in the form of a yoke 3115 ixavi a pair of depending parallel branches (only one L WI!) secured upon trunnion: smotahown) il-ZilCt are c-urnale-d inbearings (not shown) formed inth walls 78 andiili. The pin lid constitutes the thrust sustai tin m mber of the toggle tea, and its position be by an adjusting mechanism operated through a hand Wheel 1 42 as more fiully explained in said Patent No. 2,746,668. 7

The size marking die is cne 'oi' a plea lily mounted upon wheel 22?; having a hub which is securedby setserew to a shaft 234 journa' in bearings formed in the housing It A hand who 23%? l) which is slidably keyed upon the shaft the shaft to he turned to bring any desired size l. az'lung nto operative position The hand wheel integral p shaped flange .or all having a v toothed rimn eemed. lathe front wall of the housing The pin, perventsnu desired turning of the shaft 234, and the plate 2 51 upon which it is mounted can be adjusted laterally of the machine to insure proper centering of the size marking die 46 when the shaft is thus held stationary. The rim of the flange 238 carries numbers corresponding to the size marking dies, and a stationary pin 24-5 (Fig. l) cooperates with these numbers to indicate the particular die which is in operative position. if desired, an arrow may be used instead of the pin 245. A coil spring 242 (Fig. 1) interposed between a washer 244 secured to the shaft 234 and a shoulder formed internally on the hand wheel 236 normally holds the flange or dial 238 in locking engagement with the pin 240 from which position, however, it can readily be pulled forward out of engagement to permit readjustment.

The heel end gage 40 is rigidly secured upon the forward end of a member 250 which constitutes a portion of a slide indicated generally by the reference numeral 252. The shape of the slide 252, as shown in Fig. 2, is in the form of the letter H of which member 250 corresponds to the right-hand bar and a member 254 corresponds to the left-hand bar. The members 250 and 254 are inte grally connected by a portion 256 which corresponds to the cross bar of the H and which extends through an opening 258 formed in the left-hand frame wall 78. The slide 252 is slidable forwardly and rearwardly of the machine upon a lower slide 260 (Fig. 2) having a portion 262 beneath the member 250 and a portion 264 beneath the member 254, and having also a connecting portion 266 beneath the member 256 and also extending through the opening 258. Formed in the member 250 is a longi tudinal slot 268 into which extends a guiding key 270 formed integrally on the portion 262 of the lower slide 260. Secured to the under face of the portion 262 by screws 272 is a block 274 which carries a downwardly extending pin 276 (Fig. 1) on which is mounted a block 278. Rigidly secured to the shaft 234 is a worm 280 into the groove of which the block 278 slidably extends so that turning of the shaft will move the block 274 forwardly and rearwardly. The block 2'74 is guided in its forward and rearward movement by a slot 282 formed in the worktable 30 which is slidably engaged by the block. The screws 272 serve also to secure a retaining plate 284 to the upper surface of the key portion 270 of the slide member 262, the key portion being thick enough to maintain the plate 284 slightly raised for clear ance above the upper surface of the member 250 to permit relative sliding movement. The shaft 234 is maintained in its rearward operating position by a compression spring 286 which is considerably stronger than the spring 242 and which holds the end surface of the worm 280 against one of the bearing lugs of the housing 32.

Secured upon the left-hand member 264 of the lower slide 260 is a key 288 which engages a slot 290 in the member 254 of the slide 252. A clamping screw 292 (Fig. 3) threaded down into the member 264 and having a winged head 294 can be tightened to clamp a washer 296 against the upper surface of the member 254 and thereby to clamp the member 254 to the member 264, that is, to clamp the two slides together so that when the lower slide is moved by the turning of the hand wheel 236 the upper slide which carries the sole gage 40 will move in unison with it. A pointer 298 fixed upon the upper slide 252 cooperates with a stationary scale 300 secured by screws 229 to a bracket 301 mounted on the machine frame, the scale having suitable graduations to indicate the adjustment of the gage 40.

It is sometimes desirable to adjust the forward and rearward position of the heel end gage 40- independently of the hand wheel 236 and its associated size marking dies 46. To this end, the winged screw 292 can be loosened to free the upper slide 252 from the lower slide 260. A suitable adjustment can then be made of the upper slide manually, whereupon a normally loose winged screw 302 (see also Fig. 4) threaded down into a stationary key 304 can be tightened to clamp the upper slide in its adjusted position. This arrangement permits the use of any of the size marking dies while the heel end gage 40 is maintained in a fixed position. The key 304 is securely fixed upon a stationary block 305 secured to the housing 32. To permit a setting up adjustment of the scale 300, the holes in the scale through which the screws 29? extend are elongated.

The scale 300 (when set in its adjusted position) and the score marker 48 are both fixed in relation to the machine frame and therefore to each other, and the pointer 293 is fixed in relation to the gaging surface of the heel end gage 40. The scale reading of the pointer 208 therefore always indicates the distance between the score marker 48 and the heel end of the gaged sole S; that is, it indicates the position (or assumed position) of the breast line of the sole, inasmuch as the score marking is usually made at a locality which is considered to be the breast line. The graduations on the scale 300 may be made uniform. to indicate this distance in inches or millimeters if desired.

The position of the breast line, as indicated by the score marking made by the die 48, in relation to the heel end of the sole S varies not only with the length of the sole, but may also vary as between soles of the same length but intended for application to shoes having heels of different types or styles. The proper adjustment for any one type or style of heel is made by turning the dial 238 to some particular size of sole, such as size 8, loosening the winged screw 292 (the winged screw 3432 being already loose) and moving the slide 252 manually to bring the end gage 40 into whatever position is desirable for the size 8 sole intended for use with that type or style of heel. The winged screw 292 is then tightened. To obtain a proper setting of the heel gage 40 for any other size of sole intended for use with that same type or style of heel, it is only necessary to turn the dial 238 to the desired size indication.

In factories wherein only a few different types or styles of heels are used, it may be desirable to provide marks upon the scale 300 to indicate the various adjustments of relative position between the slides 252 and 260 rather than to graduate the scale in inches or other conventional units. Thus, if only three types or styles of heels are to be dealt with, only three marks on the scale will be necessary. The positions of these marks are determined by turning the dial 238 to size 8 (for example), loosening the winged screw 292, and moving the slide 252 manually into any one of the three desirable positions for the size 8 sole intended for use with the three respective types or styles of heels. The three positions of the pointer 298, as thus determined, are marked upon the scale. Once these marks have been made upon the scale, it is only necessary to bring the pointer 298 to the appropri ate mark for the type or style of heel which is to be used and then to tighten the screw 222. The dial 238 can then be turned to the appropriate size of the sole to be operated upon.

An optional device for facilitating the relative adjustment between the slides 252 and 260 is shown in Figs. 7, 8 and 9. When using this device, the winged screws 292 and 302 are omitted. The device comprises a rack 600 secured on the slide 252 and meshing with a pinion 602 fixed on a shaft 604 which rotates in a bearing 606 mounted on the slide 260. Secured to the shaft 604 is the hub of a disk 608 which carries upon its outer face a coaxial hand wheel or disk 610. Formed in the hand wheel 610 are a pair of arcuate slots 612 through which extend screws 614 for clamping the hand wheel upon the disk 608. The hand wheel 610 has formed in its periphery a plurality of notches 616 which cooperate with a detent 618 to hold the hand wheel against undesired turning. The detent 618 is mounted .upon one end of a spring bar 620 which is secured at its other end to an upstanding lug 622 integral with the bearing 606.

Each notch 616 corresponds to one of the several types or styles of heels intended to be used. The desired positions of the notches are determined by a method similar to that outlined in the preceding paragraph. The hand wheel 610 is readily detachable and interchangeable with other hand wheels having different arrangements of notches to suit whatever requirements may be called for. The arcuate slots 612 enable an accurate setting up adjustment to be made.

The sole edge gages 36 and 38 (Figs. 2 and 5) are carried indirectly upon the forward ends of a pair of arms 306 and 303 the rear portions of which are pivoted respectively upon fulcrum pins 310 and 312 secured in the worktable 3d. The arms 306 and 388 are provided with over and underlapping bell crank extensions 31.4 and 316 respectively. A square block 318 swiveled upon a pin 320 secured upon the extension 316 engages a slot 322 formed in the extension 314 and thereby coordinates the movements of the arms 386 and 388 and also of the gages 36 and 38 about a common center line extending forwardly and rearwardly of the machine. A tension spring 324 having its ends secured to the arms 306 and 388 urges the arms toward each other to a limiting position determined by a stop in the form of a screw 326 (see also Fig. 6) threaded through a block 328 secured to and depending from an outwardly extending end portion 330 of the arm 308. The block 328 just clears a shelf 332 (Figs. 2 and 6) formed on the housing 32 and the end of the screw 326 bears against an abutment in the form of a vertical wall or shoulder 334 formed on the housing 32. A compression spring 336 surrounding the shank of the screw 326 and interposed between the block 328 and a knurled head 338 formed on the screw holds the screw against undesired turning.

Seated in a groove formed in the outwardly turned portion 330 of the arm 308 is a bracket 340 extending forwardly, that is, in the general direction of the arm 308. A compression spring 342, surrounding a screw 344 which extends through a clearance hole in the bracket 340 and is threaded down through the portion 330 and into the block 328, yieldingly holds the bracket in its groove. Seated in a transverse groove in the forward end of the bracket 340 is a transverse bracket 346 adjustably clamped by a screw 350 extending through a slot 348 formed in the bracket 346 to permit adjustment transversely of the machine. The gage roll 38 is mounted for idle rotation upon a pin 358 depending from the bracket 346. A second bracket 352 in telescoping relation to the bracket 346 and adjustably secured thereto by a screw 354 extending through a slot 356 carries a guide 360 which overlies the sole S and facilitates the entry of the sole S between the gage rolls. Similar arrangements for mounting the gage roll 36 are carried by the arm 306 with the exception, however, that no stop screw corresponding to the screw 326 is necessary and provision of such a screw has been omitted. Associated with the gage roll 36 is a guide 362 similar to the guide 360.

When the use of the gage roll 38 is not desired, its supporting bracket 340 is turned ninety degrees outwardly about the screw 344, and the gage roll 36 can likewise be moved to an out-of-the-way position, as shown in broken lines in Fig. 2. It is sometimes convenient to use only the gage roll 38 and to feed the soles S against it from the left, with the gage roll 36 in out-of-the-way position. In that case the gage roll 38 is preferably held in a position of fixed adjustment by a latch 364 (Figs. 2 and 6) pivoted upon a pin 366 secured in the flange 81, the latch 364 having an inclined surface 368 which enters into camming engagement with a rounded face of the screw head 338 to hold the screw 326 against the wall 334 and thereby prevent movement of the gage roll. When in its out-of-the-way position, the latch 364 rests against a pin 378 secured in the flange 81. If desired, the gage roll 36 can be brought into operative position and the gage roll 38 moved into out-of-the-way position, and the soles S can then be fed from the right against the gage roll 36 which is also held in adjusted position by the same latch 364. When both gage rolls 36 and 38 are to be used as coordinated centering gages, the latch 364 is moved to its out-of-the-way position.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent of the United States is:

1. In a machine for operating upon shoe soles, a work table for supporting a sole, a pair of centering gages engageable with opposite edges of the sole on the work table, a pair of arms on each of which is carried one of the edge gages, connections between each edge gage and its associated arm constructed and arranged to enable the edge gage to be moved from an operative to an out-of-theway position on its arm, means for supporting the arms for coordinated movement with respect to a common center line to bring the gages into contact with the edges of the sole, resilient means acting upon the arms to urge them toward each other, and means operable at the will of the operator for securing one of said arms positively in a desired position of adjustment with respect 'to said common center line when he desires to render one of the gages stationary in operating position and to move the other gage into an out-of-the-way position.

2. In a machine for operating upon shoe soles, a work table for supporting a sole, a pair of centering gages engageable with opposite edges of the sole on the work table, a pair of arms on each of which is carried one of the edge gages, connections between each edge gage and its associated arm constructed and arranged to enable the edge gage to be moved from an operative to an outof-the-way position on its arm, means for supporting the arms for coordinated movement with respect to a common center line to bring the gages into contact with he edges of the sole, resilient means for urging the arms toward each other, a stop screw threaded through one of said arms, an abutment engageable by one end of said stop screw to limit the approach of said arms toward each other under the influence of the resilient means, and a latch movable to and from a position of engagement with the opposite end of said stop screw, in which position the latch holds the arms against movement away from each other, whereby either of said centering gages can be held positively in an adjusted operating position determined by said stop screw while the other centering gage can occupy an out-of-the-way position.
